Barometric pressure and its effects

What Is Barometric Pressure and How Does It Feel?

Barometric pressure is important. You need to know as much about it as possible so that you can figure out if it’s having an adverse effect on your health.

This article is going to have tons of valuable information. Please continue reading to understand everything about barometric pressure.

When you’re finished reading it, please share it with your friends to help them reduce negative effects. They should also know what barometric pressure is. That way, they understand more about their health.

What Is Barometric Pressure?

Barometric pressure is a measurement of air pressure within the atmosphere. Specifically, it’s the measurement of weight caused by the air molecules at a particular point on Earth. This pressure can constantly change and is always different based on where the reading took place.

Origin of Pressure

The atmosphere consists of many gases, so it must have weight. It’s amazing that the Earth has just the right mixture of nitrogen and oxygen so that people can live here. It wasn’t easy to achieve that mixture, and it changes slightly with each day, hour, and minute.

Variable Gases

  • Water vapor – 0 to 4 percent
  • Carbon dioxide – 0.034 percent
  • Ozone – 0.000004 percent
  • Carbon monoxide – 0.00002 percent
  • Sulfur dioxide – 0.000001 percent
  • Nitrogen oxide – 0.000001 percent
  • Dust, soot, and more – 0.00001 percent

Permanent Gases

  • Nitrogen – 78.08 percent
  • Oxygen – 20.95 percent
  • Argon – 0.93 percent
  • Neon – 0.0018 percent
  • Helium – 0.0005 percent
  • Methane – 0.0001 percent
  • Hydrogen – 0.00005 percent
  • Xenon – 0.000009 percent

If the Earth was any closer to the sun, such intense heat could cause the gas to escape, similar to how vapor escapes from boiling water. On Venus, temperatures can go as high as 900 degrees. However, Mercury offers an average temperature of just 500 degrees. Also, if the Earth was smaller, the gravitational pull might be reduced, so the atmosphere could get lost in space.

On the other hand, if the Earth was bigger, more gases might stay in the atmosphere because there was more gravitational pull. For example, hydrogen is the most common gas in the world. However, the atmosphere doesn’t hold a lot of it. What’s present combines with oxygen to form a low concentration of water vapor.

Hydrogen and many compounds of it aren’t heavy enough to be held down by the gravitational pull. That means they can escape, and that’s good! Those hydrogen compounds are dangerous and explosive. Typically, those gases are found on other planets, which is why humans can’t live there.

In effect, there’s the perfect planet that’s the right distance away from the sun and the right size. That unique arrangement is responsible for the pressure and variations.

Air, Its Weight, and How Does It Feel?

Air has weight, so if you climbed a tall mountain, you risk getting altitude sickness. Typically, people have to acclimatize to the new altitude before hiking on mountains. Most people believe that there’s less oxygen available at a high altitude, but that’s incorrect!

Only 20 percent of the atmosphere contains oxygen. The rest is made up of 78 percent nitrogen and 1 percent other gases. Therefore, the oxygen at sea level is the same as at high altitudes. The difference is that there isn’t as much pressure and density up there.

The pressure above your head is what pushes the air into the lungs and squeezes the oxygen out of it and into the blood. When that pressure diminishes, there’s less air pushed into your lungs. That means less oxygen gets into the blood. There’s a lessening of the atmospheric pressure, not available oxygen.

There are highs and lows that everyone experiences where they live. Basically, the sun’s heat varies all over Earth, and so do temperatures. That could mean that the warm air rises and the heavier, cold air sinks. However, that doesn’t happen either because the planet rotates.

That distorts the wind patterns so much that the air gets twisted to the right motion direction for each hemisphere. In general, high pressure is often associated with fair/good weather. These “domes” of pressure press down, and the low-pressure systems have “valleys” with less dense air. When the air pressure is increased, the temperature rises and the air holds more water vapor. Anything forming as rain dissipates before it gets to you.

Barometric Pressure Effects on Health

Though barometric pressure might not be responsible for headaches and other ailments all the time, it could be. Many people notice issues when there’s a fall in the barometric pressure. That signals a weather change like a storm.

What Are the Symptoms?

The change in barometric pressure could cause you to feel these symptoms:

  • Migraines or headaches – The environment is a huge trigger for migraines. Many people believe that they have a weather trigger. In most cases, migraines are triggered by biological or environmental changes, and this includes barometric pressure.
  • Blood pressure – The circulatory system includes veins, arteries, and the heart. Blood pressure focuses on the strength and rate of the heart and resistance within the blood vessels. Barometric pressure can affect your blood pressure.
  • Joint pain – Falling barometric pressures can make joint pain worse.


Here are the causes for those symptoms relating to a change in barometric pressure:

  • Migraines or headaches – A person’s head is made up of sinuses, or air pockets. They have air at equilibrium with atmospheric pressure. If there’s a change, even slightly, that affects the head and the air inside the body.
  • Blood pressure – When it’s cold, the blood vessels constrict, so the blood pressure increases. It takes more pressure to move through that narrow space. The blood pressure can also be affected by a sudden weather pattern change.
  • Joint pain – Many researchers believe that barometric pressure changes the fluid’s viscosity in the body to trigger a pain response from the nerve endings.

Tips on How to Prevent and Treat Barometric Pressure Effects

  • Relax the body and mind as much as possible.
  • Use deep breathing techniques to lower blood pressure and reduce migraines.
  • Don’t overdo it on those days. Get more rest as needed.
  • Drink more fluids.
